Usage note

Expressions like all the farther and all the higher occur chiefly in informal speech: This is all the farther the bus goes. That's all the higher she can jump. Elsewhere as far as and as high as are generally used: This is as far as the bus goes. That's as high as she can jump.
Although some object to the inclusion of of in such phrases as all of the students and all of the contracts and prefer to omit it, the construction is entirely standard.

Word Origin and History for all better

all

Old English eall "all, every, entire," from Proto-Germanic *alnaz (cf. Old Frisian, Old High German al, Old Norse allr, Gothic alls), with no certain connection outside Germanic.

Combinations with all meaning "wholly, without limit" were common in Old English (e.g. eall-halig "all-holy," eall-mihtig "all-mighty") and the method continued to form new compound words throughout the history of English. First record of all out "to one's full powers" is 1880. All-terrain vehicle first recorded 1968. All clear as a signal of "no danger" is recorded from 1902. All right, indicative of approval, is attested from 1953.
